Free AI Dubbing Software — Dub Any Video Into Any Language

AI dubbing is the process of using artificial intelligence to automatically transcribe, translate, and re-voice a video into a different language — replacing the original audio with a new AI-generated voice track, often with synced captions. It replaces the traditional dubbing workflow (a human transcriber, a translator, a voice actor, and a studio session) with a single automated pipeline: speech-to-text turns the spoken audio into a timed transcript, machine translation adapts that transcript into the target language, and a text-to-speech model reads the translated script aloud in a new voice, timed to match the original. AI Dubbing Studio runs this entire pipeline from one desktop app — Whisper for transcription, context-aware AI translation, and around 400 Microsoft Edge neural voices across 72 languages — with the translated script editable line by line before any voice is generated, so a bad auto-translation never has to become a wasted render.

AI Dubbing Studio offers a free 3-day trial with 3 dubs per day and no credit card required. After the trial, you can choose a one-time lifetime license or a monthly plan for unlimited dubbing.

AI Dubbing Studio transcribes your source audio with Whisper, generating a word-level timed transcript that works across noisy backgrounds, multiple speakers, and a wide range of accents. That transcript is then translated into your target language using context-aware AI translation — adapting tone, idioms, and sentence structure rather than a literal word-for-word swap — and you can review and edit every line before generating any audio. Once you're happy with the script, AI Dubbing Studio generates a natural-sounding AI voice for it (or you can preview and pick from around 400 available voices first), and can burn word-highlighted captions directly into the exported video, timed to the new dubbed audio. Transcription, translation, and voice generation run through your own Groq or OpenAI API key rather than a bundled cloud service, so you're billed directly by the provider at their published rates.

AI Dubbing Studio supports 72 languages, with source and target language chosen independently, and around 400 realistic AI voices spread across them.

Yes. The whole translated script is editable line by line before any voice is generated, and you can listen back to any line in the project's chosen voice with your edits applied.

Yes — every voice includes a sample in its own language and accent, so you can hear how it actually sounds before picking it for your project.

Yes. AI Dubbing Studio burns word-highlighted captions directly into the exported video, timed to the new dubbed audio, and also exports separate .srt and .vtt files. Right-to-left scripts render in the correct reading order.

AI dubbing is significantly faster and cheaper than hiring voice actors per language, and it's editable — you can regenerate a line instantly if a translation needs a tweak, without re-booking a studio session.

Not yet — transcription, translation, and voice generation currently run through online AI models, so an internet connection is required. There's no offline dubbing mode at this time.

AI Dubbing Studio's own license is either a $10/month plan for unlimited dubs or a $50 one-time lifetime license, after a free 3-day trial with 3 dubs a day. On top of the license, transcription and translation run on your own Groq or OpenAI API key rather than a bundled fee, so you're billed separately by whichever provider you choose, at their published rates. For a typical 30-minute video, that's roughly $0.02–$0.06 on Groq's Whisper Large v3 Turbo, or $0.09–$0.18 on OpenAI's gpt-4o-mini-transcribe or Whisper — usually under $0.25 total in API usage, with translation adding only a fraction of a cent more. Voice generation itself is free and doesn't require an API key, since it uses the bundled Microsoft Edge voices. See the API cost breakdown below for the full pricing sources.

Yes. AI Dubbing Studio's transcription and translation run on your own Groq or OpenAI API key, added once in Settings — you're billed directly by the provider you choose, at their published rates, with no markup from us. Voice generation uses the bundled Microsoft Edge voices and doesn't need a key.
